Frequently Asked Questions

You connect Microsoft 365 Copilot to the StackOne MCP gateway via a custom MCP server added in Copilot Studio: open your agent → Tools → Add a tool → New tool → Model Context Protocol, paste the StackOne gateway URL, choose OAuth 2.0, and save. See Microsoft Learn. Requires Copilot Studio + M365 Copilot licenses.
You can connect Microsoft 365 Copilot to 470+ live MCP servers through StackOne, spanning CRM, HRIS, ATS, ticketing, and finance — Salesforce, Workday, Greenhouse, and more. Each is reachable through one gateway URL instead of wiring up servers app by app. Browse the full list in the directory on this page, or build your own.
Microsoft 365 Copilot ships first-party enterprise integrations (Salesforce, ServiceNow, Workday, SAP, Adobe) plus partner agents via Copilot Studio. StackOne adds the other 470+ — every app reachable through one Custom MCP connection instead of one per app, auth managed once in the dashboard, and tool definitions loaded only when relevant to the prompt.
Credentials sit at three layers: the StackOne MCP server record (OAuth 2.0 in Copilot Studio Tools, managed by Power Platform admins), SaaS connector credentials (server-side in your StackOne dashboard), and per-user OAuth or session tokens (server-side, scoped per user). StackOne stores OAuth tokens and API keys, refreshes them automatically, and only exposes the actions you've authorized to the agent.
Skip the StackOne MCP gateway when any of these is true:
  • Microsoft's first-party Copilot agents (Salesforce, ServiceNow, Workday, SAP, Adobe) already cover your apps
  • You use only a handful of actions across a few apps
  • You don't need multi-tenancy or per-action scoping
  • Prompt injection isn't a concern
  • Your provider already does tool discovery and server-side execution
